The invention relates to a mixed magneto-electric generator with magnetic crowns for converting the rotational mechanical energy into electric energy, in particular for wind turbines for medium and weak winds. According to the invention, the generator comprises at least one module located in a housing (1) and having a double magnetic stator (S) with a solenoidal stator (6) with coils (u) circularly-arranged and joined with epoxy resin, fixed between two crowns (2, 2') of ring-shaped magnet type with large diameter, with the poles on their faces, and a rotor (R) formed of two rotor disks (7, 7') which frame the solenoidal stator (6), formed of n magnetic shields (8, 8') consisting of thin magnets (m) with the poles on their faces, repulsively-arranged in relation to the magnetic crowns (2, 2') on a rotor support-disk (e), which is fixed on a rotor shaft (4) with the ends fixed in a bearing (5,5') within a cage (a, a') fixed on a cover (b, b') of the generator housing (1) the metallic shaft (4) having on one end a collector (C) formed of an electrically insulated sleeve (i) on which two semicylindrical commutator bars (k, k') made of copper, are attached in contact with a pair of lamellar commutator brushes (j-j'), to which the connection wires of some copper disks (3, 3') or some Tesla spirals (3'') of homopolar generator are attached, to which the magnetic shields (8,8') are adhered by means of some ferromagnetic shields (d). |
